WISE Software Interface Specification for v4; RvB_rex12; (WSDC D-I189) SIS Written by Howard McCallon, version 1.5, 02/08/2011 Interface Name: RvB (Reference-vs-Band file) Type of Interface: ASCII file in IPAC table format Read By: PRex/gnDSTR (Distortion Fitter) ..................... J.W. Fowler/ H.L. McCallon Written By: PRex/SFPRex (Single-Frame Position REconstruction) .. H.L. McCallon/ J.W. Fowler DESCRIPTION: One RvB file is generated for each band in the frameset. Each band file includes the band-frame positions of sources associated with 2MASS reference stars. The 2MASS star positions have been mapped into band-frame coordinates as well. When many of these files are used together they provide the data needed for gnDSTR to compute distortion coefficients. Additional information is provided by flags indicating which bands were used/rejected for b2r measurements in the SFPRex/FSFitR fit. These data could be useful at some future date to select a subset of the b2r measurements for gnDSTR use. RvB file formats of all four bands are identical, with descriptive text in the headers documenting each column variable. Note: The "co-sigma" of a pair of variables relates to the covariance as sqrt(abs(cov))*sign(cov) EXAMPLE: \ Reference-vs-Band (RvB) file for W1 (written by SFPRex ver 1.98 B10208 on 8-02-11 at 11:11:28) \ \ KEY WORDS: \ X position of band-frame center pivot (pix) \BFXPIV = 508.5000000000 \ Y position of band-frame center pivot (pix) \BFYPIV = 508.5000000000 \ X band-frame scale (deg/pix) \BFXSCALE= -0.000766416943 \ Y band-frame scale (deg/pix) \BFYSCALE= 0.000761279669 \ \ COLUMN HEADER DESCRIPTIONS: \ ig = merge group number assigned by SFPRex \ ib = band number \ ie = WISE extraction number \ xfd = Distorted X b-frame pos of WISE ext (pix) \ yfd = Distorted Y b-frame pos of WISE ext (pix) \ xfe = X b-frame pos of WISE ext w/dstr-cor (pix) \ yfe = Y b-frame pos of WISE ext w/dstr-cor (pix) \ sigxe = sigma X band-frame pos of WISE ext (pix) \ sigye = sigma Y band-frame pos of WISE ext (pix) \ sigxye = co-sigma XY band-frame pos of WISE ext (pix) \ xfr = pos of ref mapped to X band frame (pix) \ yfr = pos of ref mapped to Y band frame (pix) \ sigxr = X sig pos of ref mapped to band frame (pix) \ sigyr = Y sig pos of ref mapped to band frame (pix) \ sigxyr = XY co-sig of ref mapped to band frame (pix) \ 2MASS_ID = 2MASS reference ID \ b2rFLGS = ic=band#; N=>no mch, U=>mch used, R=mch rej \ dxf = xfe-xfr difference (pix) \ dyf = yfe-yfr difference (pix) \ dmag = WISE-Ref magnitude difference (mag) \ RAr = RA of reference star (deg) \ DECr = DEC of reference star (deg) \ frmID = Unique frame ID \ FT = Field Tag (CF=central;LL=lower-left;UL=upper-left;UR=upper-right;LR=lower-right) \ |ig |ib|ie |xfd |yfd |xfe |yfe |sigxe |sigye |sigxye |xfr |yfr |sigxr |sigyr |sigxyr |2MASS_ID |b2rFLGS|dxf |dyf |dmag |RAr |DECr |frmID |FT| |i |i |i |r |r |r |r |r |r |r |r |r |r |r |r |c |c |r |r |r |r |r |c |c | | | | |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix |pix | | |pix |pix |mag |deg |deg | | | |null |nu|null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |null |nu| 2 1 2 503.7490 674.1470 504.2381 674.1418 0.1161 0.1381 -0.0159 504.1922 674.1048 0.0217 0.0219 0.0000 06005105-6644395 UUUU 0.0459 0.0370 0.1490 90.212731 -66.744331 02266b010 CF 3 1 3 977.0790 472.1740 977.4262 472.0464 0.0720 0.0871 0.0216 977.3879 472.0730 0.0217 0.0255 -0.0000 06035185-6629162 UUUN 0.0383 -0.0265 0.2052 90.966080 -66.487846 02266b010 CF 4 1 4 852.1890 833.3590 851.9050 832.9087 0.1368 0.1186 0.0201 851.9255 832.9139 0.0217 0.0219 0.0000 06034782-6646437 UUUN -0.0205 -0.0052 -0.0536 90.949279 -66.778809 02266b010 CF 5 1 5 560.9680 978.6060 559.8515 978.4673 0.1283 0.1298 -0.0148 559.7687 978.5150 0.0217 0.0219 0.0000 06015822-6657096 UUUN 0.0828 -0.0477 0.1775 90.492603 -66.952682 02266b010 CF 7 1 7 891.5760 347.8450 891.7200 347.8749 0.1211 0.1123 0.0035 891.7057 347.9400 0.0254 0.0219 0.0000 06025688-6625050 UUUN 0.0143 -0.0651 0.0490 90.737011 -66.418076 02266b010 CF 8 1 8 330.2610 64.9140 329.6413 64.9686 0.1489 0.1643 -0.0337 329.6952 64.8963 0.0254 0.0255 0.0000 05581222-6620235 UUUN -0.0538 0.0723 0.0140 89.550949 -66.339882 02266b010 CF 9 1 9 949.2020 185.9650 948.7319 186.3542 0.1229 0.1226 0.0044 948.7626 186.3371 0.0254 0.0219 0.0000 06025931-6617152 UUUN -0.0307 0.0171 0.0680 90.747153 -66.287575 02266b010 LR
